Which expression is equivalent to 4x4x4x4x4x4x4x4?
a. 4 x 8
b. 8^4
c. 8x8
d. 4^8
I think D.
D is correct.
If you do the math for both, you can see they both get the answer of 65,536.
4 x 4 x 4 x 4 = 256
4 x 4 x 4 x 4 = 256
256 x 256 = 65,536
4^8 = 4 x 4 x 4 x 4 x 4 x 4 x 4 x 4 = 65,536
So, D is correct.
I hope this helps! :)
Also, if you do the math for each answer, they don't equal 65,536 when solved.
A. 4 x 8 = 12 -(This one is not the answer because of the answer of 12.)
B. 8^4 = 8 x 8 x 8 x 8 = 4,096 -(This is also not the answer because of 4,096.)
C. 8 x 8 = 64 -(Similar to A, but this is not the answer to the problem.)
So again, D is correct because is equals 65,536 when solved.
I hope this helps you more! :)
To determine which expression is equivalent to 4x4x4x4x4x4x4x4, we can simplify the expression using exponentiation. Each "4" is being multiplied together 8 times, so we can rewrite it as 4^8.
Therefore, the correct answer is option d. 4^8.
